In their own words
Breadbin466
Breadbin466 is a free Commodore 64 emulator written in Rust, focused on modeling one PAL Assy 250466 machine. Its cycle-driven emulation covers the MOS 6510 CPU and VIC-II video timing and generation, including bus arbitration. The SID sound model draws on a physical datecode 2286 chip and models oscillator, DAC, mixing, and filter behavior. Its Commodore 1541 drive emulation includes a separate CPU, VIAs, mechanics, GCR read channel, IEC communication, fastloaders, and protected-disk behavior. Other modeled hardware includes CIA interfaces, a 1351 proportional mouse, a Datassette with TAP playback and recording, cartridges, and a 512 KB REU. It supports D64, G64, NIB, NBZ, and D7Z disk images, with tools for image creation, conversion, and space reclamation. The integrated debugger provides breakpoints, disassembly, history, and configurable tracing. Native menus and Inspector windows are provided on macOS, Windows, and Linux. Version 0.99.0 is described as feature-complete, with broader testing still remaining before 1.0.
Hoxs64
Hoxs64 is a free Commodore 64 emulator for Microsoft Windows, written by David Horrocks. Its documentation describes cycle-exact emulation and pixel-exact VIC emulation of a C64C, without emulating the grey dot bug. A simulated 1541 floppy drive supports reading and writing, while the tape player is read-only. The emulator handles D64, G64, P64, FDI, TAP, PRG, P00, T64, and CRT files, and includes state saving, a debugger, full-screen mode, and configurable keyboard and joystick controls. Cartridge support covers Action Reply, Easy Flash, Ocean, Magic Desk, and Commodore REU 1750 options in 512K or 16MB configurations. Multiple cartridges are unsupported, and mounting one disables the REU option. Listed downloads are 32-bit and 64-bit version 1.1.2.9. Requirements include Windows 10 or 11, DirectX 11.1, the Microsoft Visual C++ 2022 runtime, 4 GB RAM, and a DirectX 11 graphics card with pixel shader 4.0. Installation requires the runtime and copying ZIP contents into one directory.
